The Arrow-Dot Test as a Predictor of Police Officer Performance
In the course of validating a test battery for the selection of police officers (Baehr, Furcon, & Froemel, 1969), project personnel were searching for objectively scored, pencil-and-paper measures of behavior variables. One product of this search was an adaptation of the Arrow-Dot subtest of the four-part IES test battery (Dombrose & Slobin, 1958). This adaptation was designed for group administration and for improved reliability as a possible predictor of performance. Intercorrelational analysis and factor analysis of intercorrelations with other potential predictor variables and performance criteria provided some information on the nature of the Arrow-Dot scores. The test's ability to predict police officers' performance was assessed through multiple regression analyses of its scores both as independent predictors and as contributors of unique variance in a wider predictor battery. Its usefulness for diagnosis of specific problems in police officers' performance was also investigated. Application in five additional studies permitted an exploration of the “characteristic” Arrow-Dot dimension profile for police officers.
